Produce a human-readable semantic diff (added/removed/changed tables, columns, measures, relationships) between a baseline snapshot and either another snapshot or the live model. Ideal for PR review and pre-deploy
AI agents call model_diff to retrieve information from Power BI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads and compares two model states to produce a diff report. It does not modify, execute, delete, or commit any changes — it is purely an informational/analytical read operation used for PR review and pre-deploy inspection.

Produce a human-readable semantic diff (added/removed/changed tables, columns, measures, relationships) between a baseline snapshot and either another snapshot or the live model. Ideal for PR review and pre-deploy. It is categorised as a Read tool in the Power BI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Power BI MCP Server MCP server in PolicyLayer and add a rule for model_diff: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Power BI MCP Server. Nothing to install.
model_diff is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the model_diff rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for model_diff. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
model_diff is provided by the Power BI MCP Server MCP server (sulaiman013/powerbi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
